The formula for frequency is: f (frequency) = 1 / T (period).
f = c / λ = wave speed c (m/s) / wavelength λ (m).
The formula for time is: T (period) = 1 / f (frequency).
The formula for wavelength is λ (m) = c / f
λ = c / f = wave speed c (m/s) / frequency f (Hz).
The unit hertz (Hz) was once called cps = cycles per second.
c = λ × f λ = c / f = c × T f = c / λ
Differentiate the Speed of the Medium:
Speed of Sound or Speed of Light
Choose: Speed of sound in air at a temperature of 20°C: c = 343 m/s
or speed of radio waves and light in a vacuum: c = 299,792,458 m/s.
The propagation speed of electrical signals via optical fiber is about 9/10
the speed of light, that is ≈ 270,000 km/s.
The propagation speed of electrical signals via copper cables is about 2/3
the speed of light, that is ≈ 200,000 km/s.
Speed of sound c = 343 m/s also equates to 1235 km/h, 767 mph, 1125 ft/s.
There are four parts to a wave:
wavelength, period, frequency, and amplitude
Changing the frequency (hertz, Hz) does never change the amplitude and vice versa
The Angular Frequency is ω = 2π × f
Given is the equation: y = 50 sin (5000 t)
Determine the frequency and the amplitude.
Answer: The amplitude is 50 and ω = 5000.
So the frequency is f = 1/T = ω / 2 π = 795.77 Hz.
To use the calculator, simply enter a value.
The calculator works in both directions of the ↔ sign.
Answer:
The formula for frequency is: f (frequency) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m).
